Definitions

  • the temperature of the liquid preferably is maintained within the desired temperature range for a certain time. This can be achieved by any means known to the person skilled in the art; preferably this is achieved by injecting vaporised liquid into the liquid or by heating coils.
  • P3 is commensurate with P2 in that the liquid is recycled, thus saving liquid. Further, the plant according to P3 is preferred if the extruder and the pelletiser are working at a temperature such that large amounts of liquid are needed for cooling within the pelletiser. In such a case the pellet slurry obtained from the pelletiser has a low concentration which requires a significantly larger treatment tank to treat the same amount of pellets in the same time. Thus, by concentrating the pellet slurry in liquid separator (118), a smaller treatment tank can be used. This reduces the costs.
  • the plastic material from extruder 1 is pelletised in pelletiser 2 and transported by water via conduit 3 to water separator 4 wherein some, preferably 40 % to 98 % and more preferably 70 % to 95 % of the pelletising water is removed.
  • the pellets together with the warm pelletising water are then fed via conduit 5 through an inlet into treatment tank 6.
  • this inlet is located next to the top of treatment tank 6.
  • this inlet is located next to the bottom of treatment tank 6.
  • the water quantity is kept at 5 to 200 vol.%, preferably at 5 to 100 vol.% above the theoretical minimum to fill the volume between the pellets. This means that sufficient water is present to disperse the pellets in the water within treatment tank 6.
  • the liquid within treatment tank 6 is kept at T b -25 °C to T b , preferably at T b -10 °C to T b of the liquid, wherein T b is the boiling point of the liquid at the applied pressure.
  • Cooling water is fed via conduit 23 to pellet water cooler 22 and removed through conduit 23a for cooling and the cooled pellet water is then introduced via conduit 24 into pelletiser 2.
  • the vapours from the treatment tank 6 are vented via conduit 38 to off-gas knock out drum 39 equipped with off-gas condenser 40, to recover main part of the water before the vented light hydrocarbons are routed via conduit 41 to downstream processes (like recovery, fuel gas system, etc.). Cooling water is supplied through conduit 42 and removed through conduit 42a. The recovered water is fed via conduit 43 to intersection 29 where it is combined with the hot degassing water from conduit 28.
  • Propane, ethylene and hydrogen were continuously introduced into a loop reactor having a volume of 500 dm 3 .
  • a polymerisation catalyst prepared otherwise according to Example 3 of WO 95/35323 except that the average particle size of the silica carrier was 25 ⁇ m, was introduced into the reactor together with triethyl aluminium so that the molar ratio of aluminium in the activator to titanium in the solid component was 15.
  • the loop reactor was operated at 95 °C temperature and 60 bar pressure.
  • Ethylene content in the fluid phase in the slurry reactor was 6.5 % by mole and the ratio of hydrogen to ethylene was 450 mol/kmol.
  • the production rate of polymer was 30 kg/h.
  • the polymer produced in the loop reactor had an MFR 2 of 380 g/10 min and a density of 975 kg/m 3 .
  • the polymer was mixed with 2000 ppm of Irganox B561 and 2000 ppm of calcium stearate and extruded into pellets in a counterrotating twin-screw extruder JSW CIM90P.
  • the polymer pellets had a density of 944 kg/m 3 and an MFR 5 of 0.85 g/10 min.
  • Into the pellets was then added a carbon black masterbatch so that its amount was 5.75 % of the total composition and pelletised.
  • the used carbon black masterbatch has been prepared by compounding 58.6 wt. % LDPE, 39.5 wt. % carbon black and 1.9 wt.% of Irganox 1010 (distributed by Ciba).
  • the carbon black masterbatch has an MFR 21 of 14 g/10 min.
  • Example 9 The procedure of Example 9 was repeated except that the process conditions in the gas phase reactor were adjusted to obtain a polymer with a density of 950 kg/m 3 and MFR 5 of 0.24 g/10 min. Further, the ratio of water to pellets was 10. The results are shown in table 6 below.
